Application October chines, and'has for its object to provide a device of this 'characterfcomprising a vbracket adapted"k tobe attached toi-'a support and having thereon a receptacle from which grease is forced ydownwardly through a discharge `port intothefcham-V ber of a grease gun supported in a` verticalposition below the receptacle.

A further object is to provide the bracket with` Y a receptacle shelfon which the receptacle-issup.

` the receptacle for closingthe discharge aperture therein and disposed in side oftheshelf.v A further object is to provide a recess lin the forward side ofthe shelf incommunication. with va chamber in-.the upper the chamber ofthe shelf thereby'allowing access ing and closing the same.

VA furtherk object is to provide a grease gun supporting bracket beneath the receptacle and tothe slidable closure vforthe receptacle for open-i held in axial relation' with the axis of therecep-y tacle and the discharge opening by a member mounted on the bracket and having spring grip-V ping arms between whichthe body of the grease gun is forced. Also to provide a supporting aperturev in the 'bracket for the discharge spout of the gun and shaped whereby the discharge spout will be received thereinand will pivotally move as the gun body is forced between the spring arm. v`A furtherobject is to4 provide means. lwhereby the gun supporting .bracket may beadjusted towards and awayr from the receptacle and a screw actuated piston within the Vreceptacle for forcng the contents from the receptacleas desire v With the aboveand other objects in view the invention resides 'in the combination and arrangement of parts as hereinafter set forth, shown in the drawing, described and claimed, it being understood that changes in the precise embodi- `ment of the invention may be made within the scope of what is claimed without departing from the spirit of the invention.

. Referring to the drawing, the numeral I-desig- Anates a support which may be a post or the side of a building,l and secured tov said support by means of .screws 2 is achambered bracket 3 infthe chamber 4 of which is slidably mounted U-shaped members 5,to whichare secured through vertical slots 6 in the chambered member 3 thergun Vsupporting bracket I and the piston shaft bracket 8. It will be noted by this structure that these brackets may be adjusted upwardly or down,- wardly as desired according to the size of. grease receptacle 9 being used..

The lower bracket 1 is'provided adjacent its outer end withadownwardly and inwardly 1inclined aperture in, which extends entirely there# through, and which aperture receivesthe spout II oifthe grease gun I2 in a manner whereby as the grease gun is moved upwardly and inwardf ly to Vthe vertical position shownin `Figure '1; it will be forced between the spring gripping arms I3 or the gun holding bracket I4, which ispreff .erably formed from springmaterial andinc'iines downwardly and inwardlyfand is anchored atll' tothebracket 1. Itwill be noted thatthe gun I2 is supported in a vertical axial position in ref' Vlationto. the receptacle 9 with its upper endopen so `that greasedischarged from thewreceptacle 9 will enter the gun forrecharging purposes, By adjustably mounting the bracket 'I, it will be noted that different size grease guns may be Vlled, as

y said grease rguns vary-in length.

Extending routwardly frozn the chainbe'red member-3 is a substantially circular horizontally' through the ears 2.0 carried by the straps,` hencey it will be seen there is a positive gripping operaand which closure is adapted to be opened by the Y operator at the start of a discharge operation and be closed at the end of the discharge operation, thereby cutting off the flow of grease from the receptacle to the igrease gun l2. The forward end of the shelf I6 is provided Ywith a recess 24,

which 'allows access to the iianged forward endn portion 25 ofthe closure 22, however said recess 24 merges into a chamber 26 in theupper side of the shelf l 6, in the bottom of which is providedV a discharge aperture 21, which is in'aXial relation to lthe discharge port 2! in the bottom-of i the receptacle, and the axis ofthe grease gun l2` to be filled. It will be noted that the guides 23 lit closely in the bottom of the recess 26, so'that said recess will not fill with lubricant during a 2 filling operation. e Y 1 Grease is forced from the greasenlreceptacle 9 by means of a piston 28 slidably mounted therein,

and which piston has pivotally connected -at 29 to theupper side thereof a threadedshaft 30, which extends upwardly through thenreceptacle coger 3|, which may be raised for refilling purposes along with the piston, and is Athreaded at 32 through the upper adjustable bracket 8 Vand .terminates in a crank 3,3 adapted to :be grasped by the `operator for forcing, the piston vZildownwardly or upwardlyV as desired.

Y, yFrom the above it, will. be seen that aigrease gun filling machine isprovided which is simple in construction, theparts reduced to a minimum, and one wherein akgrease gun is supported in, a verticalf position, beneath a 'grease receptacle for filling purposes. It will also be seen that the flower, end of the receptacle is positivelygripped by the straps I7 and that the slidable "closure carred'by .the loiwer end of the receptacle is received in achamber inthe upper side of the shelf through which Vthe discharged grease isV forced.

. The device. is particularly adapted lfor use in consupported on the fupper side ofV said bracket,`

means forl forcing grease from saidreceptacle, means carried by the bracket and gripping the 1 receptacle adjacent the lower end of the receptacle'and'the upper side of the 'bracket and means foresupporting a grease-gun in 'al position where thergreaseforced from the receptacle will enter the grease gun; Y

2. The combinationV with a grease gun filling machine comprising a receptacle from thelower e end of which grease is forced through adi-scharge port, of means for supporting' a grease gun 'in ax'- i'alirelation toV the discharge port," lsaid means comprising a bracket beneathV the receptacle and having a` greasegun receiving aperture therein in axial relation tothe discharge port of the receptacle, and spring gripping arms carried by the bracket and spaced above the bracket and adapted to grip opposite sides of a grease gun and maintain the same in axial relation tothe discharge port of the receptacle. y

V3. A grease gunlling machine comprising a bracket, a shelf carried by vsaid bracket, a greaseV `warddirectionthrough a port in the shelf, means for supporting a grease gun beneath said port and a separable flexible strap surrounding and gripping; the lower end of .the receptacle and anchored to the shelf.

4, Aldevice asset forth'in claim 3 including a hin'gedconnection between the parts of the separableflexible strap and located to one side of the receptacle and securing means connecting the free ends of said strap.

.L A device-as set vforth in claiin- 3 including a slidable `closure carriedv by the lower end of the receptacle en ,iidfV disposed in a chamber in the shelf, said chamber terminatingdina recess inthe forward endxof thershelfinto which the closure extends, thereby allowing access to the closure lfor opening and closing thezsame,

6. A grease gun iling rmachine -comprisinga bracket adapted to be. attached to arsupport, a

Vadapted to be forced downwardly for forcing grease Vfrom the receptacle, an operating screw for.

said piston, an adjustable'bracket through which said operating screw extends, Va, .discharge` port extendingthrough theA shelf in'axial relation to the dischargejfport inf the 'bottom 'of the receptacle," a grease Vgun'supprorting bracket-beneath the-receptacle gripping -means calried by the bracket for supporting saidrgrease gun and means whereby said grease gunlbracket may be adjusted upwardly and downwardlyg 11 :if 7. The combination 'with ag-rease gun filling machine froniwhich grease is forced downwardly into a 'verticallysupported grease gun, Yof means fonsupporting said grease gun, said means comprising Va bracket, a downwardly; and inwardly inclined greasegun lspout.receiving'aperture extending. throughv said bracket. 1and in which said grease.v gun vspout 'willfengage `opposite sides of the aperture when moved to a vertical position and a member' carried by'said bracket and adapted 5to' Vgrip/fopposite vsides Hof-jthe grease gun above the bracket andl maintainthe same in a vertical position. f Y' LOWELL BOWEN, vALLitN T; McPHERsoN.
